Soichiro Yagami: It's been over a month since Kira started killing criminals again; and, as far as I'm concerned, that's all the proof I need to be sure that my son isn't Kira. So, then, all that's left is for you to be sure. One way or another, when I get out of here it will be with my son.

Misa Amane: Honestly, all this time I never pictured you as an old man, Mr. Stalker. Soichiro Yagami: I am not your stalker. I'm a detective with the NPA. Misa Amane: What? Hey, wait. I remember now. You told me I was being arrested for being the second Kira. You mean that was for real? You know, you're a stalker. There's no way the police would blindfold me and tie me up all fetishy like that. Anyways, it's kinda weird that you have my hands and feet all tied up even though you're planning to let me go. Soichiro Yagami: Please, just keep quiet.

Soichiro Yagami: Light, my son, from one murderer to another, I'll see you in Hell!

[English dub] Light Yagami: If they're trying to find out L's identity, it's probably because they want to kill 'im and they need that information to do it. Soichiro Yagami: This isn't good. We're already short-handed enough as it is, and now we have to worry about Coil, too. L: It's quite all right. The detective known as Geraldo Coil is me. Soichiro Yagami: Oh. L: It's quite simple, really. Three of the greatest detectives in the world - L, Coil, and Deneuve - they're all actually me. It's been my experience that people who try to find me usually fall for this. I'll give you this strawberry if you keep it a secret, okay?

[last lines] Soichiro Yagami: But if there's supposed to be eight, why are there only seven.

Soichiro Yagami: Kira is pure evil. We can all agree on that, but recently I've started thinking of this whole situation in a different way. What is truly evil is the power to kill people, and any person who has come to possess this kind of power is cursed. No matter how you use it, no true happiness can be obtained like that, not by killing other people.
